Long Beach GP: Lexus LFA (pro driver Tanaka) vs IS-F CCS-R racing car (Gushi)
Hotlaps from both cabin.
I could not believe how a stock LFA destroyed even a dedicated stripped out IS-F CCS-R racing car

Also surprised. The IS-F CCS-R is stripped down so weighs less than the LFA, and has a ton of reinforcements stiffening up the body to improve cornering dynamics. I guess it just shows how good a car the LFA is from the bottom up.
Lexus has repeatedly stated they did not make any direct modifications to the IS F engine in the CCS-R conversion, but that doesn't mean it's making the same hp. Stated CCS-R modifications such as increased airflow, revised intake, racing exhaust, etc., all can increase hp.
That said, it's obvious from the video that the LFA has a power-to-weight advantage.

The #003 LFA 451 wheel HP LFA was where on the same FP dyno and same day a 300 HP STi dyno'ed at only 190 wheel HP. FP said it was a very "pessimistic" dyno.
Depending on the dyno, LFAs have dyno'ed from 450 wheel HP to 470 - 480 wheel HP all the way up to 515 wheel HP (MD automotive).
The weight reduction is a far bigger factor for the CCS-R, but then again the power difference is just way too big to overcome by weight reduction.

Although, LFA will tend to pull harder away after its 125 - 126 mph trap speed. For example, 0 - 165 mph has been recorded in LFA coming in only 21 seconds.

BTW, a modified IS F needs a ton of extra juice to hit 400hp dyno. That automatic transmission sucks up a lot of power. Stock IS Fdynos around 350 IIRC. Not going to make it to 400hp at the wheels just off intake/exhaust.

I still think my statement is pretty close. LFA at or around 560hp. IS-F at or around 420hp. Even this IS-F, I would think makes maybe 20hp more. But maybe the LFA is making more power than advertised.

lems/icodes ISFs ( from japan ) are doing great work with the ISF . the ccsr is stripped down alot more than lems/icodes isf. lems/icode isf fuji lap time 154.3
stock lfa 155.342
now im not at all saying the F is dominating the LFA... just friendly conversation lems/icode is doing great thing with the F.

LFA's Potenza tires are considered some of the most average tires in the supercar world. Not even ranked high-grip. Michelin SS and Pilot Cup racing slick tires are way more stickier than the one's LFA is wearing.
